1.Effectiveness and Safety of Newer Antidiabetic Medications for Ramadan Fasting Diabetic Patients.
Mudher Mikhael E J Diabetes Res. 2016;2016:6962574. doi: 10.1155/2016/6962574. Epub 2016 Aug 24.
Hypoglycemia is the most common side effects for most glucose-lowering therapies. It constitutes a serious risk that faces diabetic patients who fast during Ramadan (the 9th month in the Islamic calendar). New glucose-lowering classes like dipeptidyl peptidase-4 (DPP-4) inhibitors, glucagon-like peptide 1 receptor agonist (GLP-1 RA), and sodium-glucose cotransporter-2 (SGLT-2) inhibitors are efficacious in controlling blood glucose level with less tendency to induce hypoglycemia and thus may constitute a good choice for diabetic patients during Ramadan. This study reviews the safety and efficacy of newer glucose-lowering therapies during Ramadan. This study was accomplished through a careful literature search about studies that assess the benefit and side effects of these new glucose-lowering therapies during Ramadan during September 2015. Vildagliptin, sitagliptin, liraglutide, exenatide, and dapagliflozin were the only studied glucose-lowering therapies. All of the studied newer glucose-lowering therapies except dapagliflozin were associated with reduced risk to induce hypoglycemia. Gastrointestinal upset was common with the usage of liraglutide while increased thirst sensation was common with dapagliflozin.
2.Combination of the insulin sensitizer, pioglitazone, and the long-acting GLP-1 human analog, liraglutide, exerts potent synergistic glucose-lowering efficacy in severely diabetic ZDF rats.
Larsen PJ;Wulff EM;Gotfredsen CF;Brand CL;Sturis J;Vrang N;Knudsen LB;Lykkegaard K Diabetes Obes Metab. 2008 Apr;10(4):301-11. doi: 10.1111/j.1463-1326.2008.00865.x.
OBJECTIVE: ;Severe insulin resistance and impaired pancreatic beta-cell function are pathophysiological contributors to type 2 diabetes, and ideally, antihyperglycaemic strategies should address both.;RESEARCH DESIGN AND METHODS: ;Therapeutic benefits of combining the long-acting human glucagon-like peptide-1 (GLP-1) analog, liraglutide (0.4 mg/kg/day), with insulin sensitizer, pioglitazone (10 mg/kg/day), were assessed in severely diabetic Zucker diabetic fatty rats for 42 days. Impact on glycaemic control was assessed by glycated haemoglobin (HbA(1C)) at day 28 and by oral glucose tolerance test at day 42.;RESULTS: ;Liraglutide and pioglitazone synergistically improved glycaemic control as reflected by a marked decrease in HbA(1C) (liraglutide + pioglitazone: 4.8 +/- 0.3%; liraglutide: 8.8 +/- 0.6%; pioglitazone: 7.9 +/- 0.4%; vehicle: 9.7 +/- 0.3%) and improved oral glucose tolerance at day 42 (area under the curve; liraglutide + pioglitazone: 4244 +/- 445 mmol/l x min; liraglutide: 7164 +/- 187 mmol/l x min; pioglitazone: 7430 +/- 446 mmol/l x min; vehicle: 8093 +/- 139 mmol/l x min). A 24-h plasma glucose profile at day 38 was significantly decreased only in the liraglutide + pioglitazone group.
3.Management of hyperglycemia associated with pasireotide (SOM230): healthy volunteer study.
Breitschaft A;Hu K;Hermosillo Reséndiz K;Darstein C;Golor G Diabetes Res Clin Pract. 2014 Mar;103(3):458-65. doi: 10.1016/j.diabres.2013.12.011. Epub 2013 Dec 25.
AIMS: ;Pasireotide, a multireceptor-targeted somatostatin analogue with efficacy in Cushing's disease and acromegaly, can affect glucose metabolism due to inhibition of insulin secretion and incretin hormone responses. A study was therefore conducted to evaluate different antihyperglycemic drugs in the management of pasireotide-associated hyperglycemia.;METHODS: ;This was a 1-week, Phase I, open-label study. Healthy male volunteers were randomized to pasireotide 600 μg sc bid alone or co-administered with metformin 500 mg po bid, nateglinide 60 mg po tid, vildagliptin 50mg po bid, or liraglutide 0.6 mg sc qd. An oral glucose tolerance test (OGTT) was performed on days 1 and 7 to evaluate effects on serum insulin, plasma glucose and glucagon levels. Safety/tolerability and pharmacokinetic effects were also evaluated.;RESULTS: ;Ninety healthy male volunteers were enrolled (n=18 per arm). After 7 days of treatment, plasma glucose AUC post-OGTT increased by 69% with pasireotide alone. The effect was reduced by 13%, 29%, 45% and 72% with co-administration of metformin, nateglinide, vildagliptin and liraglutide, respectively. On day 7, compared with pasireotide alone, the decrease in serum insulin was attenuated with nateglinide, metformin, liraglutide and vildagliptin co-administration (levels were 3%, 6%, 34% and 71% higher, respectively).
